DISCHARGE-PIPE FOR DREDGING AND OTHER MACHINES.

SPECIFICATION forming part of Letters Patent No. 282,700, dated August'7, 1883.

Application filed February 5, 1883. (N 0 model.)

To all whom it may concern.-

Be it known that 1, JAMES M. BUOKLE'Y, of Portland, in the county ofMultnomah and State of Oregon, have invented certain new and usefulImprovements in Discharge-Pipes for Dredging and other Machines, ofwhich the following is a full, clear, and exact description.

This invention consists in a revolving discharge=pipe and itsconnections, as hereinafter described, for dredging -machines,sandpumps, and excavators, whereby the material passing through saidpipe is prevented from settling therein, thereby aiding the water in itsdischarging action and reducing the volume of water necessary to forcethe earthy or analogous material through the discharge-pipe.

Reference is to be had to the accompanying drawings, forming a part ofthis specification,

corresponding parts in all the figures.

Figure 1 represents a side elevation of a .revolving discharge-pipeconnected with a hopper, and a discharge-pipe from a dredging orexcavating machine arranged to deliver into said hopper. Fig. 2 is anend view, upon a larger q scale, of said revolving dischargepipe, withthe roller support on which it rests. Fig. 3 is a longitudinal sectionof a portion or length of the revolving discharge-pipe, with gear forrotating the same, and a stuffing-box for connecting it with the pipefrom the hopper. Fig. 4 is an end view of. the revolving discharge-pipewith its hopper-connection, together with engine and gears for drivingsaid pipe. Fig. 5 is a side view of the revolving dischargepipe,connected by a flexible attachment, without the interposition of ahopper, with the main or stationary discharge-pipe from the said pump ordredgingmachine.

Referring, in the first instance, or more particularly to Figs. 1, 2, 3,and 4 of the drawings, A indicates a dredging-machine of any suitableconstruction, and B the water on which it floats; O, a bank alongside ofsaid water, and D a frame erected on such bank for support of areceiving-hopper and gear end or portion of the revolving or rotarydischarge-pipe E.

F is the main or stationary diseharge-pipe from the excavator ordredging-machine, which may have a flexible joint-piece, b, to providefor the'adjustment of its delivery end relatively to a hopper, G, intowhich the water and material to be discharged are delivered from thepipe F.

The revolving discharge-pipe E, which carries off the material thatpasses through the hopper, is driven or rotated by an engine, H, orother motor, through gearing c d, or otherwise. Said pipe E is mainlysupported on roller-bearings e e, to provide for its easy rotation, andhas a stuffing-box, f, 011 its inlet end, for connection with andarrangement around the outlet-pipe 9 from the hopper.

The receiving section or length of the 'revolvin g discharge-pipe E ismade sufficiently heavy to carry the stuffing box f, gear 0, and to Worksteady. in close bearings e, and the remaining portion of said pipe maybe con nected to itby flanges or otherwise. By said pipe E being thusfitted to revolve at its stuffing-box end around the discharge-pipe fromthe hopper, a ready clearance is provided for the material discharged bythe dredging-machine, excavator, or sand-pump, and the quantity of waternecessary to carry off the dis charge is materially reduced.

Fig. 5 shows substantially the same ar- 7 rangeinent as in Fig. 1, sofar as the revolving pipeE, with its stuffing-box f and gear 0, isconcerned; but instead of said pipe connecting with an outlct-pipe froma hopper, it is connected direct or in a close manner by a flexibleattachment or hose, I, with the pipe F of the dredging or other machine.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. The rotary discharge-pipe E, for dredging and otheranalogous machines, constructed or provided with a gear-wheel, c, andwith a stuffing-box, f, arranged at or near its receiving end,essentially as described.

2. The combination of the close bearings e e and roller-bearings e 0With the rotary discharge-pipe E, the wheel or gear 0 thereon,-

and the stufiing-box f, substantially as speci- 3. In dischargingconnections or attachments for dredging and other analogous inachines,the combination of the hopper G,
